6. Tighten the rear roller bolt on the side of the treadmill toward which the running belt is moving using
a 3/4" socket wrench.
For example: If the running belt moves to the right of the belt tracking slots, tighten the bolt on the
right side of the frame, tighten about 1/2 of a turn (clockwise) and wait 30 seconds. If the running
belt does not move back to the center of the belt tracking slots, make another adjustment to the
same bolt. Once the running belt has been adjusted closer to the center of the belt tracking slots,
use about 1/4 of a turn until the running belt has been stabilized.

7. Check the belt tension after the running belt has been centered.
Make sure the running belt tension is tight enough so that the running belt does not slip or hesitate
when stepped on. Walk on the treadmill at 3.5 - 4 mph (5.6 - 6.4 kph) and every 4th to 5th step throw
your weight into your step to feel if the running belt is slipping. If slipping is felt, confirm it is the
running belt slipping and not the drive belt. With the hood cover removed, observe movement at the
drive belt and front roller.
Do not over tighten the running belt. Over tightening the running belt can cause the belt to stretch
and require replacement. Continue procedure until running belt stops slipping.
8. Check running belt for centering position.
If running belt is not centered, perform steps 5 and 6.
Check Running Belt and Deck Surfaces
The running belt and deck should be checked periodically for any excessive wear. In an effort to make
sure that the running belt operates properly, visually inspect the belt often to make sure that there are
no tears or fraying in the belt material. The running belt should be replaced every 15,000 miles (24,140
km). The running deck should be flipped every 15,000 miles (24,140 km) and replaced every 30,000
miles (48,280 km). A service prompt will appear at this interval and the parts will need to be replaced.
